Diabetes and Stroke: Impact of Novel Therapies for the Treatment of Type 2 Diabetes Mellitus.

Type 2 diabetes mellitus (T2DM) is a significant risk factor for stroke. Nevertheless, the evidence supporting stringent glycemic control to reduce macrovascular complications, particularly stroke, is not as clear as for microvascular complications. Presently, risk reduction strategies are based on controlling multiple risk factors, including hypertension, dyslipidemia, glycemia, smoking, and weight. Since 2008, new pharmacological therapies for treating T2DM have been required to undergo trials to ensure their cardiovascular safety. Remarkably, several novel therapies have exhibited protective effects against the combined endpoint of major cardiovascular events. Evidence from these trials, with stroke as a secondary endpoint, along with real-world data, suggests potential benefits in stroke prevention, particularly with glucagon-like peptide 1 receptor agonists. Conversely, the data on sodium-glucose cotransporter type 2 inhibitors remains more controversial. Dipeptidyl peptidase 4 inhibitors appear neutral in stroke prevention. More recent pharmacological therapies still lack significant data on this particular outcome. This article provides a comprehensive review of the evidence on the most recent T2DM therapies for stroke prevention and their impact on clinical practice.

Serum urate change among gout patients treated with sodium-glucose cotransporter type 2 inhibitors vs. sulfonylurea: A comparative effectiveness analysis.

OBJECTIVE: To investigate the serum urate (SU) change among gout patients initiating SGLT2i, and to compare with sulfonylurea, the second-most widely used glucose-lowering medication after metformin. METHODS: We conducted a cohort study of patients with gout and baseline SU >6 mg/dL who had SU measured within 90 days before and after SGLT2i or sulfonylurea initiation. Using multivariable linear regression, we compared SU change among SGLT2i initiators between those with and without diabetes and then compared SU change between SGLT2i and sulfonylurea. RESULTS: We identified 28 patients with gout initiating SGLT2i (including 16 with diabetes) and 28 patients initiating sulfonylurea (all with diabetes). Among SGLT2i initiators, the mean within-group SU change was -1.8 (95 % CI, -2.4 to -1.1) mg/dL, including -1.2 (-1.8 to -0.6) mg/dL and -2.5 (-3.6 to -1.3) mg/dL among patients with and without diabetes, respectively, with an adjusted difference between those with and without diabetes of -1.4 (-2.4 to -0.5) mg/dL. The SU did not change after initiating sulfonylurea (+0.3 [-0.3 to 1.0] mg/dL). The adjusted SU change difference between SGLT2i vs. sulfonylurea initiation was -1.8 (-2.7 to -0.9) mg/dL in all patients. The SU reduction persisted regardless of urate-lowering therapy or diuretic use and the presence of diabetes, chronic kidney disease, or heart failure. CONCLUSION: Among patients with gout, SGLT2i was associated with a notable reduction in SU compared with sulfonylurea, with a larger reduction among patients without diabetes. With their proven cardiovascular-kidney-metabolic benefits, adding SGLT2i to current gout management could provide streamlined benefits for gout and its comorbidities.

[The effect of a medicinal plant preparation on the frequency of episodes of exacerbation of recurrent cystitis and metabolic parameters in patients with type 2 diabetes mellitus taking glyphlosins].

BACKGROUND: The problem of recurrent urinary tract infections (UTI) in patients with type 2 diabetes mellitus (DM 2) is relevant, especially when there is a combination of predisposing factors, such as female gender, history of UTI episodes, and therapy with sodium glucose cotransporter type 2 (SGLT-2) inhibitors, and the choice of effective and safe means could cause some difficulties, including ina terms of the burden of antibiotic resistance. AIM: To evaluate the effectiveness and safety of the phytoproduct Canephron® N for the prevention of exacerbations of recurrent cystitis and the effect on metabolic parameters in patients with type 2 diabetes taking SGLT-2 inhibitors. MATERIALS AND METHODS: Prospective, randomized, open, parallel group study in 60 women. The main group took the drug Canephron® N for 3 months. The main parameters for evaluating were the frequency of recurrence of cystitis, level of albuminuria and LDL-cholesterol peroxidation product - malondialdehyde. RESULTS: Within 3 months of taking Canephron® N, exacerbations of chronic cystitis were diagnosed 2 times less often, a decrease in albuminuria was found in the form of an increase in the proportion of patients with an optimal level of albuminuria by 20%, a 50% reduction in the frequency of the initial increase in albuminuria, and the absence of moderate albuminuria in all patients at the end of course of therapy. A decrease in the level of MDA by 1.4 times was noted (p=0.019). CONCLUSION: Thus, the herbal drug Canephron® N can be used for accompanying therapy and prophylactic treatment in patients with recurrent cystitis on the background of DM 2, taking SGLT-2 inhibitors. The course of therapy should last at least 3 months.

Dapagliflozin Improved Cardiac Function and Structure in Diabetic Patients with Preserved Ejection Fraction: Results of a Single Centre, Observational Prospective Study.

Sodium-glucose cotransporter inhibitors (SGLT2i) have demonstrated a reduction in cardiovascular events in diabetes and heart failure (HF). The mechanisms underlying this benefit are not well known and data are contradictory. The purpose of this study is to analyse the effect of dapagliflozin on cardiac structure and function in patients with normal ejection fraction. Between October 2020 and October 2021, we consecutively included 31 diabetic patients without prior history of SGLT2i use. In all of them, dapagliflozin treatment was started. At inclusion and during six months of follow-up, different clinical, ECG, analytical, and echocardiographic (standard, 3D, and speckle tracking) variables were recorded. After a follow-up period of 6.6 months, an average reduction of 18 g (p = 0.028) in 3D-estimated left ventricle mass was observed. An increase in absolute left ventricle global longitudinal strain (LV-GLS) of 0.3 (p = 0.036) was observed, as well as an increase in isovolumetric relaxation time (IVRT) of 10.5 ms (p = 0.05). Moreover, dapagliflozin decreased the levels of plasma creatin-kinase (CK-MB) and atrial natriuretic peptide (ANP). In conclusion, our data show that the use of SGLT2i is associated with both structural (myocardial mass) and functional (IVRT, LV-GLS) cardiac improvements in a population of diabetic patients with normal ejection fraction.

Novel Drugs for the Management of Diabetes Kidney Transplant Patients: A Literature Review.

The management of diabetes and renal failure is changing thanks to the appearance of new drugs such as glucagon-like peptide 1 receptor agonists (GLP1-RA) and sodium-glucose cotransporter type 2 inhibitors (SGLT2i) that have benefits in terms of survival and cardiorenal protection. Based on the potential mechanisms of GLP1-RA, kidney transplant recipients (KTRs) could benefit from their effects. However, high-quality studies are needed to demonstrate these benefits, in the transplant population, especially those related to cardiovascular benefits and renal protection. Studies with SGLT2i performed in KTRs are much less potent than in the general population and therefore no benefits in terms of patient or graft survival have been clearly demonstrated in this population to date. Additionally, the most frequently observed side effects could be potentially harmful to this population profile, including severe or recurrent urinary tract infections and impaired kidney function. However, benefits demonstrated in KTRs are in line with a known potential effects in cardiovascular and renal protection, which may be essential for the outcome of transplant recipients. Better studies are still needed to confirm the benefits of these new oral antidiabetics in the renal transplant population. Understanding the characteristics of these drugs may be critical for KTRs to be able to benefit from their effects without being damaged. This review discusses the results of the most important published studies on KTRs with GLP1-RA and SGLT2i as well as the potential beneficial effects of these drugs. Based on these results, approximate suggestions for the management of diabetes in KTRs were developed.

[Clinical and practical management of sodium-glucose cotransporter type 2 inhibitors in patients with chronic kidney disease]. / Manejo clínico-práctico de los inhibidores del cotransportador sodio-glucosa tipo 2 en pacientes con enfermedad renal crónica.

The discovery of the nephroprotective role of sodium-glucose cotransporter type 2 (iSGLT2) inhibitor drugs in people with type 2 diabetes mellitus (DM 2) following the results obtained in the respective cardiovascular safety trials led to a change in the approach to diabetic kidney disease in recent years, positioning this group in the first step in the treatment of this comorbidity. The publication of the results of the DAPA-CKD study with dapagliflozin, demonstrating its benefit in slowing the progression of chronic kidney disease (CKD) in patients with and without DM, has opened a new age in the management of this pathology. These drugs are also safe and easy to use for the clinician. This article reviews the management of iSGLT2 in patients with diabetic and non-diabetic CKD.

Rationale and design of the Biventricular Evaluation of Gliflozins effects In chroNic Heart Failure: BEGIN-HF study.

AIMS: Sodium-glucose cotransporter type 2 inhibitors (SGLT-2i) represent a unique class of anti-hyperglycaemic agents for type 2 diabetes mellitus that selectively inhibit renal glucose reabsorption, thereby increasing urinary excretion of glucose. Several studies have demonstrated the cardioprotective effects of SGLT-2i in patients with heart failure (HF), unrelated to its glucosuric effect. It is unclear whether the benefits of SGLT-2i therapy also rely on the improvement of left ventricular (LV) and/or right ventricular (RV) function in patients with HF. This study aimed to evaluate the effect of SGLT-2i on LV and RV function through conventional and advanced echocardiographic parameters with a special focus on RV function in patients with HF. METHODS AND RESULTS: The Biventricular Evaluation of Gliflozins effects In chroNic Heart Failure (BEGIN-HF) study is an international multicentre, prospective study that will evaluate the effect of SGLT-2i on echocardiographic parameters of myocardial function in patients with chronic stable HF across the left ventricular ejection fraction (LVEF) spectrum. Patients with New York Heart Association Class II/III symptoms, estimated glomerular filtration rate > 25 mL/min/1.73 m2 , age > 18 years, and those who were not previously treated with SGLT-2i will be included. All patients will undergo conventional, tissue-derived imaging (TDI), and strain echocardiography in an ambulatory setting, at time of enrolment and after 6 months of SGLT-2i therapy. The primary endpoint is the change in LV function as assessed by conventional, TDI, and myocardial deformation speckle tracking parameters. Secondary outcomes include changes in RV and left atrial function as assessed by conventional and deformation speckle tracking echocardiography. Univariate and multivariate analyses will be performed to identify predictors associated with primary and secondary endpoints. CONCLUSIONS: The BEGIN-HF will determine whether SGLT-2i therapy improves LV and/or RV function by conventional and advanced echocardiography in patients with HF irrespective of LVEF.

Renal and Cardiovascular Metabolic Impact Caused by Ketogenesis of the SGLT2 Inhibitors.

Sodium-glucose cotransporter type 2 inhibitors (SGLT2i) are glycosuric drugs that were originally developed for the treatment of type 2 diabetes mellitus (T2DM). There is a hypothesis that SGLT2i are drugs that are capable of increasing ketone bodies and free fatty acids. The idea is that they could serve as the necessary fuel, instead of glucose, for the purposes of cardiac muscle requirements and could explain antihypertensive effects, which are independent of renal function. The adult heart, under normal conditions, consumes around 60% to 90% of the cardiac energy that is derived from the oxidation of free fatty acids. In addition, a small proportion also comes from other available substrates. In order to meet energy demands with respect to achieving adequate cardiac function, the heart is known to possess metabolic flexibility. This allows it to switch between different available substrates in order to obtain the energy molecule adenosine triphosphate (ATP), thereby rendering it highly adaptive. It must be noted that oxidative phosphorylation in aerobic organisms is the main source of ATP, which is a result of reduced cofactors. These cofactors include nicotine adenine dinucleotide (NADH) and flavin adenine dinucleotide (FADH2), which are the result of electron transfer and are used as the enzymatic cofactors that are involved in the respiratory chain. When there is an excessive increase in energy nutrients-such as glucose and fatty acids-which occur in the absence of a parallel increase in demand, a state of nutrient surplus (which is better known as an excess in supply) is created. The use of SGLT2i at the renal level has also been shown to generate beneficial metabolic alterations, which are obtained by reducing the glucotoxicity that is induced by glycosuria. Together with the reduction in perivisceral fat in various organs, such alterations also lead to the use of free fatty acids in the initial stages of the affected heart. Subsequently, this results in an increase in production with respect to ketoacids, which are a more available energy fuel at the cellular level. In addition, even though their mechanism is not fully understood, their vast benefits render them of incredible importance for the purposes of further research.

Empagliflozin inhibits excessive autophagy through the AMPK/GSK3ß signalling pathway in diabetic cardiomyopathy.

AIMS: Sodium-glucose cotransporter 2 inhibitors have beneficial effects on heart failure and cardiovascular mortality in diabetic and non-diabetic patients, with unclear mechanisms. Autophagy is a cardioprotective mechanism under acute stress conditions, but excessive autophagy accelerates myocardial cell death leading to autosis. We evaluated the protective role of empagliflozin (EMPA) against cardiac injury in murine diabetic cardiomyopathy. METHODS AND RESULTS: Male mice, rendered diabetics by one single intraperitoneal injection of streptozotocin and treated with EMPA (30 mg/kg/day), had fewer apoptotic cells (4.9 ± 2.1 vs. 1 ± 0.5 TUNEL-positive cells %, P < 0.05), less senescence (10.1 ± 2 vs. 7.9 ± 1.2 ß-gal positivity/tissue area, P < 0.05), fibrosis (0.2 ± 0.05 vs. 0.15 ± 0.06, P < 0.05 fibrotic area/tissue area), autophagy (7.9 ± 0.05 vs. 2.3 ± 0.6 fluorescence intensity/total area, P < 0.01), and connexin (Cx)-43 lateralization compared with diabetic mice. Proteomic analysis showed a down-regulation of the 5' adenosine monophosphate-activated protein kinase (AMPK) pathway and upstream activation of sirtuins in the heart of diabetic mice treated with EMPA compared with diabetic mice. Because sirtuin activation leads to the modulation of cardiomyogenic transcription factors, we analysed the DNA binding activity to serum response elements (SRE) of serum response factor (SRF) by electromobility shift assay. Compared with diabetic mice [0.5 ± 0.01 densitometric units (DU)], non-diabetic mice treated with EMPA (2.2 ± 0.01 DU, P < 0.01) and diabetic mice treated with EMPA (2.0 ± 0.1 DU, P < 0.01) significantly increased SRF binding activity to SRE, paralleled by increased cardiac actin expression (4.1 ± 0.1 vs. 2.2 ± 0.01 target protein/ß-actin ratio, P < 0.01). EMPA significantly reversed cardiac dysfunction on echocardiography in diabetic mice and inhibited excessive autophagy in high-glucose-treated cardiomyocytes by inhibiting the autophagy inducer glycogen synthase kinase 3 beta (GSK3ß), leading to reactivation of cardiomyogenic transcription factors. CONCLUSION: Taken together, our results describe a novel paradigm in which EMPA inhibits hyperactivation of autophagy through the AMPK/GSK3ß signalling pathway in the context of diabetes.

Narrative review investigating the nephroprotective mechanisms of sodium glucose cotransporter type 2 inhibitors in diabetic and nondiabetic patients with chronic kidney disease.

Background and aims: Outcome trials using sodium glucose cotransporter type 2 inhibitors have consistently shown their potential to preserve kidney function in diabetic and nondiabetic patients. Several mechanisms have been introduced which may explain the nephroprotective effect of sodium glucose cotransporter type 2 inhibitors beyond lowering blood glucose. This current narrative review has the objective to describe main underlying mechanisms causing a nephroprotective effect and to show similarities as well as differences between proposed mechanisms which can be observed in patients with diabetic and nondiabetic chronic kidney disease. Methods: We performed a narrative review of the literature on Pubmed and Embase. The research string comprised various combinations of items including "chronic kidney disease", "sodium glucose cotransporter 2 inhibitor" and "mechanisms". We searched for original research and review articles published until march, 2022. The databases were searched independently and the agreements by two authors were jointly obtained. Results: Sodium glucose cotransporter type 2 inhibitors show systemic, hemodynamic, and metabolic effects. Systemic effects include reduction of blood pressure without compensatory activation of the sympathetic nervous system. Hemodynamic effects include restoration of tubuloglomerular feedback which may improve pathologic hyperfiltration observed in most cases with chronic kidney disease. Current literature indicates that SGLT2i may not improve cortical oxygenation and may reduce medullar oxygenation. Conclusion: Sodium glucose cotransporter type 2 inhibitors cause nephroprotective effects by several mechanisms. However, several mediators which are involved in the underlying pathophysiology may be different between diabetic and nondiabetic patients.

Sodium Glucose Cotransporter Type 2 Inhibitors Improve Cardiorenal Outcome of Patients With Coronary Artery Disease: A Meta-Analysis.

Objective: Sodium glucose cotransporter type 2 inhibitors (SGLT-2i) are beneficial for cardiorenal outcomes in patients with type 2 diabetes mellitus (T2DM), heart failure (HF) or chronic kidney disease (CKD). However, whether or not the patients with coronary artery disease (CAD) have prognostic benefit from SGLT-2i treatment has not been fully studied. The purpose of this meta-analysis is to determine the prognostic benefit of SGLT-2i administration in CAD patients. Methods: We searched the PubMed, Embase and Cochrane Library from inception until October 15, 2021. We included randomized controlled trials (RCTs) reporting the effect of SGLT-2i on major adverse cardiovascular event (MACE), hospitalization for heart failure (HHF), cardiovascular (CV) death and cardiorenal parameters in CAD patients. Hazard ratio (HR) with 95% confidence interval (CI) and mean difference (MD) from trials were meta-analyzed using fixed-effects models. Results: Nine trials enrolling 15,301 patients with CAD were included in the analyses. Overall, SGLT2i were associated with a reduced risk of MACE (HR: 0.84; 95% CI 0.74-0.95; I2 = 0%), HHF (HR: 0.69; 95% CI 0.58-0.83; I2 = 0%) and a composite of CV death or HHF (HR: 0.78; 95% CI 0.71-0.86; I2 = 37%) in CAD patients. Compared with control group, estimated glomerular filtration rate (eGFR) level decreased less in SGLT-2i group (mean difference [MD] = -3.60, 95% CI, -5.90 to -1.30, p = 0.002; I2 = 0%). Conclusions: SGLT-2i can improve cardiorenal outcomes in CAD patients. Further RCTs and real world studies are need to investigate the effect of SGLT2i on CAD patients.

Women and Diabetes: Preventing Heart Disease in a New Era of Therapies.

Despite major advances in cardiovascular research over the past decade, women with type 2 diabetes have a high risk of cardiovascular events. Several factors contribute to the poor prognosis for women, including higher levels of frailty and comorbidities, but their cardiovascular risk is underestimated and there is suboptimal implementation and uptitration of new evidence-based therapies, leading to high morbidity and mortality. Recent studies highlight the need for better management of diabetes in women that can be pursued and achieved in light of recent results from randomised controlled trials demonstrating evidence of the benefits of new therapeutic strategies in improving cardiovascular outcomes and quality of life of women covering the entire cardiovascular continuum. This review critically discusses the multiple benefits for women of new pharmacological treatments, such as glucagon-like peptide-1 receptor agonists, sodium-glucose cotransporter type 2 inhibitors (SGLT2i), proprotein convertase subtilisin/kexin type 9 inhibitors, inclisiran, icosapent ethyl and bempedoic acid in preventing cardiovascular events, and treatments, such as angiotensin receptor neprilysin inhibitors, SGLT2i, vericiguat and omecamtiv mecarbil, for preventing heart failure.

Beneficial effects of sodium glucose cotransporter 2 inhibitors on left ventricular mass in patients with diabetes mellitus.

BACKGROUND: Sodium glucose cotransporter 2 inhibitor (SGLT2i) has recently been suggested to reduce the risk of cardiovascular events. Left ventricular hypertrophy (LVH) is associated with cardiovascular events. Diabetic macroangiopathy is a crucial complication in patients with diabetes mellitus (DM). This study examined the effect of SGLT2i on LVH in patients with type 2 DM (T2DM). METHODS: The retrospective cohort study was conducted in consecutive outpatients with T2DM from 2010 to 2020. Left ventricular mass index (LVMI) was used as an indicator of LVH based on echocardiography. The minimum follow-up period was 1 year. After propensity score-matching for clinical profiles, patients who underwent annual echocardiography twice for a routine checkup and took SGLT2i were defined to the SGLT2i group, whereas patients without SGLT2 inhibitors were defined to the non-SGLT2 group. SGLT2i was administered after baseline echocardiography followed by a second examination. RESULTS: LVMI levels in the SGLT2i group (n = 169) significantly decreased from baseline compared with those in the non-SGLT2i group (n = 169), % changes in LVMI2.7(g/m2.7 ) in median (interquartile ranges [IQR]) were - 7.7 (-18.7, 2.5) vs -3.6 (-14.3, 5.8), respectively, P = 0.017). In a subgroup analysis, LVMI levels in the patients who had LVH in the SGLT2i group more significantly decreased than those without LVH, % changes in LVMI2.7(g/m2.7 ) in median (IQR) were -13.5 (-22.1, -2.4) vs -2.8 (-12.6, 9.8), respectively, P < 0.001). CONCLUSIONS: SGLT2i treatment was shown to improve LVH in patients with T2DM and may play a pivotal role in the future treatment of diabetic cardiovascular complications.

Effects of sodium-glucose cotransporter type 2 inhibitors on cardiovascular, renal, and safety outcomes in patients with cardiovascular disease: a meta-analysis of randomized controlled trials.

BACKGROUND: Controlled studies and observational studies have shown that sodium-glucose cotransporter type 2 inhibitors (SGLT-2i) are beneficial for the survival of patients with heart failure (HF). However, it is unclear whether SGLT-2i can provide benefit in patients with other cardiovascular diseases. Here, we conducted a systematic review and meta-analysis to determine the outcomes of cardiovascular, renal, and safety outcomes of SGLT-2i administration in patients with cardiovascular diseases. METHODS: We searched PubMed, EMBASE, Cochrane Library, Web of Science databases, and ClinicalTrials.gov databases for randomised controlled trials written in English from inception until November 1, 2020. Two reviewers independently identified randomised controlled trials comparing the effects of SGLT-2i in patients with cardiovascular disease with or without diabetes. Primary outcomes were cardiovascular outcomes and renal outcomes. Secondary outcomes were safety outcomes, including adverse endocrine outcomes and adverse infection outcomes. The effects of SGLT-2i were evaluated using RevMan5.3 software. The Cochrane risk of bias tool was used to assess study quality. RESULTS: We identified 10 randomised controlled trials (25,108 patients in the SGLT-2i group and 18,574 patients in the placebo group). Meta-analysis revealed that SGLT-2i treatment significantly reduced all-cause mortality, cardiovascular mortality, and hospitalisation for heart failure (HHF) in patients with cardiovascular disease (all-cause mortality relative risk [RR]: 0.86; 95% confidence interval [CI] 0.81-0.91; P < 0.00001; I2 = 0%; cardiovascular mortality RR: 0.85; 95% CI 0.79-0.92; P < 0.0001; I2 = 26%; HHF RR: 0.69; 95% CI 0.64-0.81; P < 0.00001; I2 = 0%). In patients with HF, mortality and HHF after SGLT-2i treatment for HF with reduced ejection fraction were significantly reduced, whereas HF with preserved ejection fraction did not differ compared with placebo treatment. Moreover, SGLT-2i induced a lower incidence of renal damage and myocardial infarction than the placebo group; however, the risk of infection, amputation, volume depletion, and diabetic ketoacidosis was higher. CONCLUSIONS: SGLT-2i had significant clinical effects on cardiovascular outcomes and significantly influenced acute kidney injury. The effects of SGLT-2i on cardiovascular disease were independent of diabetic status. Sotagliflozin could have advantages over other SGLT-2i in lowering HHF.

Association of type 2 diabetes mellitus with the development of new-onset atrial fibrillation in patients with non-ischemic dilated cardiomyopathy: impact of SGLT2 inhibitors.

The aim of this study was to investigate the association of type 2 diabetes mellitus (T2DM) with the development of new-onset atrial fibrillation (AF) for non-ischemic dilated cardiomyopathy (DCM) patients. We also tested the hypothesis that sodium glucose cotransporter type 2 (SGLT2) inhibitors reduce the risk of development of new-onset AF for non-ischemic DCM patients. We retrospectively studied 210 patients with non-ischemic DCM and sinus rhythm, mean age of 59.0 ± 16.7 years and left ventricular ejection fraction of 31.0 ± 8.2% (all < 45%). T2DM was identified in 60 patients (28.6%), and the remaining 150 patients (71.4%) were classified as non-T2DM patients. New-onset AF occurred in 21 patients (10.0%) over a median follow-up of 6.1 years. Kaplan-Meier curve analysis showed that non-ischemic DCM patients without T2DM experienced fewer occurrences of the development of new-onset AF compared with those with T2DM (log-rank p = 0.0003). Furthermore, global longitudinal strain in patients who showed development of new-onset AF was significantly lower than that in those whose sinus rhythm was preserved (6.4 ± 1.4% vs. 7.7 ± 2.2%, p = 0.01). Of the 60 non-ischemic DCM patients with T2DM, those treated with SGLT2 inhibitors experienced fewer occurrences of the development of new-onset AF than did those not treated with SGLT2 inhibitors (log-rank p = 0.040). T2DM is associated with the development of new-onset AF in non-ischemic DCM patients, and treatment with SGLT2 inhibitors can significantly reduce the development of new-onset AF. Our findings may thus offer a new insight into the management of non-ischemic DCM patients with T2DM.

Positive effect of dapagliflozin on left ventricular longitudinal function for type 2 diabetic mellitus patients with chronic heart failure.

BACKGROUND: The effect of sodium glucose cotransporter type 2 (SGLT2) inhibitor on left ventricular (LV) longitudinal myocardial function in type 2 diabetes mellitus (T2DM) patients with heart failure (HF) has remained unclear. METHODS: We analyzed data from our previous prospective multicenter study, in which we investigated the effect of the SGLT2 inhibitor dapagliflozin on LV diastolic functional parameters of T2DM patients with stable HF at five institutions in Japan. Echocardiography was performed at baseline and 6 months after administration of dapagliflozin. LV diastolic function was defined as the ratio of mitral inflow E to mitral e' annular velocities (E/e'). LV longitudinal myocardial function was assessed as global longitudinal strain (GLS), which in turn was determined as the averaged peak longitudinal strain from standard LV apical views. RESULTS: E/e' significantly decreased from 9.3 to 8.5 cm/s 6 months after administration of dapagliflozin (p = 0.020) as previously described, while GLS showed significant improvement from 15.5 ± 3.5% to 16.9 ± 4.1% (p < 0.01) 6 months after administration of dapagliflozin. Furthermore, improvement of GLS in HF with preserved ejection fraction patients was more significant from 17.0 ± 1.9% to 18.7 ± 2.0% (p < 0.001), compared to that in HF with mid-range ejection fraction and HF with reduced ejection fraction patients from 14.4 ± 2.4% to 15.5 ± 1.8% (p = 0.06) and from 8.1 ± 1.5% to 7.8 ± 2.1% (p = 0.44), respectively. It was noteworthy that multiple regression analysis showed that the change in GLS after administration of dapagliflozin was the only independent determinant parameters for the change in E/e' after administration of dapagliflozin. CONCLUSION: Dapagliflozin was found to be associated with improvement of LV longitudinal myocardial function, which led to further improvement of LV diastolic function of T2DM patients with stable HF. GLS-guided management may thus lead to improved management of T2DM patients with stable HF.

Impact of dapagliflozin on left ventricular diastolic function of patients with type 2 diabetic mellitus with chronic heart failure.

BACKGROUND: The objective of this study was to investigate the impact of sodium glucose cotransporter type 2 (SGLT2) inhibitors on left ventricular (LV) diastolic function of type 2 diabetes mellitus (T2DM) patients with heart failure (HF). METHODS: This trial was a prospective multicenter study of 58 T2DM patients with stable HF at five institutions in Japan. Patients who had been taking at least one antidiabetic drugs other than SGLT2 inhibitors started the administration of 5 mg/day of dapagliflozin. The physical examinations, blood tests, and echocardiography were performed at baseline and 6 months after administration of dapagliflozin. The primary endpoint was defined as a change in mitral inflow E and mitral e' annular velocities (E/e') between baseline and 6 months after the administration of dapagliflozin. The secondary end points consisted of a change in brain natriuretic peptide (BNP), LV mass index (LVMI) and left atrial volume index (LAVI). RESULTS: E/e' significantly decreased from 9.3 to 8.5 cm/s (p = 0.020) 6 months after administration of dapagliflozin. LAVI and LVMI significantly decreased from 31 to 26 mL/m2 (p = 0.001), and from 75.0 to 67.0 g/m2 (p < 0.001), respectively, 6 months after administration of dapagliflozin. No significant change was observed in BNP (from 27.9 to 28.9 pg/mL; p = 0.132) 6 months after administration of dapagliflozin, except for a significant decrease from 168.8 to 114.3 pg/mL (p = 0.012) in patients with BNP ≥ 100 pg/mL. CONCLUSION: This prospective multicenter trial showed the beneficial effect of SGLT2 inhibitors on LV diastolic functional parameters for T2DM patients with HF. Our findings may thus offer a new insight into the management of T2DM patients.
